Sharebot SnowWhite Club

Sharebot SnowWhite is the Sharebot DLS (Direct Laser Sintering or SLS) professional 3D printer based on laser sintering technology which consists in the sinterization of thermoplastic powders realized by a laser, layer by layer.

The main advantages of the laser sintering technology compared to other technologies are:

the possibility to create objects of any desired shape, without using supports;
the mechanical and thermal resistance of the realized objects;
the possibility to use again the left-over.

If you like to share or publish information, images, documents related to SnowWhite or laser sintering in general, send a request.

Each year we print an handbook with all the documents we receive and we share it during international exhibitions.

Thanks to Sharebot’s collaboration with Universities and Research Centers, you can stay updated on the latest developments in the SnowWhite project

Snowwhite2: Why we use a CO2 laser for our SLS 3d printers

CO2 laser-based SLS technologies, such as the Snowwhite2 and Snowwhite2-HT models, outperform diode-based systems in thermoplastic processing. A wavelength of 10.6 µm enables optimal absorption of materials such as PA12, PA11, TPU, and PP, ensuring more effective melting and fusion. This results in the production of parts characterized by high density, improved mechanical properties, and a superior surface finish.

Materials and features

The printer with its CO2 laser allows to use a wide range of professional thermoplastic powder, such as PA 12, PA 11 and TPU, which give specific properties to the realized objects. To handle particular requests, it is also possible to use charged powders which contain particles of other materials such as glass, carbon or aluminum, giving different physical, mechanical and visual properties to the final objects.

SnowWhite has the aim to bring the advantages of the sintering process to the small and medium business and to technical laboratories not only in an economic, easy and efficient way, but also keeping a professional and high quality result.

It is a printer which allows the user to “print in a click” because after a material is profiled, the printing process is completely automatic and the results are fully reproducible.

Compared to other printers based on the same technology, it’s faster in terms of setup and preparation of a job. It means that the time from the loading of the powder to the creation of the first layer can be as low as 30 minutes.

The printer medium consumption is less then 1,5 Watt/h and all the left-over powder can be used again in the next printing process. The printer requires only 300 ml of powder to start working and the building speed can reach 10 mm/h.

Sharebot SnowWhite is compatible with different powders like PA12, PA11, TPU and other charged powders. Our researchers tested many materials to be able to find the right setting to print them.
